Hello,

Anyone try this new charger? The specs make it sound super cool!

I don't think anyone has tried it yet. It doesn't get released until Feb 22nd.

But yes I have been eyeing this one for sure. The specs look awesome. I love the fact that it gives you a readout of the internal resistance of each cell and a battery quality/health check. Thats a feature that i haven't seen before. Finally a real way to tell how good the low cost lipos are vs the high dollar packs. Just that feature alone my mean it makes it into the stable for me.

Oops, I got an email about it and just posted...

I'm not quite clear on the built in balancing capabilities. Does this mean you will not need to use an external balancer? Just hook the Pack up?

That would be very slick.

Yea. The balancer is built in.

I've been using the cellpro 4s since it's release. Awesome charger. I'm impatiently awaiting the 10s version.

I have a CellPro 6s and its nice, but it is missing the built in lcd screen. You kinda just have to trust its doing the right thing unless you hook it up to the PC. It always does a nice job and keeps the batteries balanced well, but I I like to be able to see whats going on while the packs charge. Other than that its a killer charger.

Did you guys see the new Schulze chargers?

Now that's what I call a super charger.

Would that be a balancepro by any chance ? I've never seen or heard of a cellpro 6s.

Yes... BalancePro HD 6s.

Sorry.
Listen to what I mean.... Not what I say.

Totally Agree! The Cellpro 4s is a great charger! I ordered the cellpro 10s as soon as they opened it for pre-orders. Now I just have to wait for it to come in.

Let us know how you like it when it comes. I can't afford to order right now, but I really must have one as soon as possible.

Hi guys,

I have been searching information about the new 10S model myself, and fund this on another forum here (post 68).

When one pack is connected to the charger, initially, the pack is charged at the selected charge rate (or the maximum charge rate possible). Using ohm’s law, the maximum charge rate (Amps) is derived from the maximum power (Watts) the charger can produce without over-heating. Maximum power is approximately 300W measured at the charger input; currently the highest in the industry. FMA rates maximum power using a 15V DC input source. Maximum power depends on many factors including pack imbalance during charge, input (supply) voltage, output (charge) voltage, DC/DC converter efficiency (which varies between 80% and 90% depending on the relationship of supply voltage-to-charge voltage), ambient temperature, and internal operating temperature.

It looks like the 300W is a total BULLSHIT since it is input maw power only.
According to first user's feedback, the max they get seems to be about 170W of actual output.

I'd like to know what you guys think, but if that's true this totally sucks. I don't want to support a company that give BS advertisements like this. Plus, at this price, taking the real output power into account, it may not be so much of a good deal after all??

What do you think? The other forum link I gave is towards electric flyers people, they should know pretty well what they're doing. I'm affraid this information is serious.

I've read all the buzz on various forums and I ordered one of these for myself. Basically I know it will serve my needs and that FMA will be releasing firmware updates shortly which address any shortcomings of the initial release. Here is a link to a thread I started here looking for a charger:

http://www.rc-monster.com/forum/showthread.php?t=10818

and here is an awesome link showing how slick this charger is:

The video links are on the right side, video 1, 2 and 3...very good stuff.

I will of course post info when I actually get the charger (mid April likely).

In my experience FMA has done a great job of honestly marketing and supporting their products. If there is a problem with the power output, i'm sure it will be remedied in a future firmware release. As this is a brand new product, we'll have to wait and see what it brings.

[tino_ale]

As far as I know, the fact that the charger output is not 300W as advertised is not a technical problem that FMA intend to correct. If you read the quotation I have provided, FMA advertises the input power of the charger, which is indeed 300W at maximum (and apparently you need a 15VDC input to reach that power though). The actual output power is not specified, and according to users feedback, it is about 170W at most.

So you basically don't care that FMA is advertising 300W of input power (without saying so) while everyone would expect this number to refer to the output power? If you take Hyperion chargers, they do behave as advertised and there is not tweak about power.

I find this to be a purposely misleading ommission. Where any honest company would have sold the 10C as a 175W charger or 200W at most, they have choosen to sell it as a 300W charger.

Now, that said, if you are aware about the fact that this charger is not a 300W charger and still find it is a good deal, I'm not saying this is a bad charger. I'm just saying FMA hype and vicious communication about it's power limitation sucks.
